Electrochemistry of saccharinate anion at liquid interfaces

Abstract : Electrochemistry of saccharinate anion (sacc−) is studied at the liquid water|nitrobenzene (w|nb) interface by means of three-phase electrodes. Saccharinate anion can be effectively transferred across w|nb interface driven by the redox transformation of the lutetium bis(tetra-tert-butylphthalocyaninato), with a standard Gibbs energy of transfer from water to nitrobenzene of 20.17 kJ mol−1. The kinetics of transfer is estimated applying the quasireversible maximum. In addition, the influence of sacc− on the thermodynamics and kinetics of the alkali metal cations transfer is discussed.
